l I(s claims. (cl. 1464-139 y f Ihis invention relates to improvementsin machines for slicing ,stationarily-positioned ybakery products. n 1

One of the objects of `this invention is to produce a horizontal slicingmachine in which the product to be sliced is maintainedin stationaryposition and-cutting knives are mechanicallyreciprocated while beingmoved in an arcuate path through said product.

Still another object of my invention is to f provide a mechanism havingone or vmore mechanically-reciprocated, slicing knives mounted in aradially-extending operating frame Amovable in an arcuate path, combinedwith means for retaining the product to be sliced in a Xed position inthe arcuate path of the reciprocating knives in said radially-extendingand arcuately-movable operating frame, whereby conveying devices for theproductmay be 'eliminated andthe slicingmachine construction may begreatly; simplied.

Still'another object of my-invention is'to produce a horizontal slicingmachine ofthe type specified having a stationary product-supportingtable, combined with a radially-projecting operating frame pivoted atone edge. on said supporting table and free at its opposite edge toenable manual arcuate movement over saidy supporting table of said'frameabout its pivot, said operating frame having one or morehorizontally-disposed slicing knives mounted therein for .mechanicalreciprocation, power means is employed for r'eciprocating said knife orknives, and means is provided on Vsaid supporting table for maintainingthe product in a stationary position within said path of arcuatemovement of said reciprocating cutting knives.

Still another object of my invention is in a horizontal slicing machineof the 1 character specified to provide a pivoted radially-disposedoperating frame having mounted therein one or more mechanically-actuatedreciprocating knives, a stationary.product-mounting table on which saidradially-disposed operating frame is pivotally movable in an arcuatepath during mechanical reciprocating movement of said knife orknives,means on said table is provided for retaining the product in stationaryposition relatively to the said arcuately-movable operating frame andmeans is also provided on said table for supporting said operating frameduring its said arcuate movement.

Still another object of my invention is in a machine ofthe characterspecified to provide in combination with a pivotally-movable operatingframe, a motor mounted on and movable with said pivoted operating framefor' operatingvlan eccentric to reciprocate the knife or knives andthusv to cause continuous andunimpeded movement of said eccentricduringarcuate operating movement of said operating frame.

Still another object of my invention is to provide a pivotedarcuately-movable carrier member or bracket including a casing formounting eccentric mechanism adapted vto reciprocate one or more knivesin a radially-projecting operating frame and to carry in said movement amotor for actuating said eccentric mechanism, whereby saidradially-projecting operating frame isunitarily connected with saidmotor and both may be moved by hand-manipulation to produce an unimpededslicing engagement of said knife or knives with a stationary bakeryproduct. Y

Still another object of my invention is in a machine of the characterspeciiied, to utilize for the reciprocation of thevslicing vknife vorknives mechanism that will be strong and durable and nwilleliminatestrains and stresses that have here- `bifurcated connecting rodadapted to engage and embraceV intermediate itsends the articulatingjoint or -connection with the eccentric rod or strap, and to enable suchjoint orconnection to be varticulated within a rod-bearing member havinga'diameter'adapted to receive and cooperate with. said heavy bifurcated-or two-part rod 'so as to permit both articulation of the joint andreciprocation within said bearing, andl thus to avoid much of thestrains and stresses heretoforev imposed upon such rods andto eiectuallyresist such strains as'may be imposed thereon.

. With these and other objects in view, the invention comprises thecombination of members and. arrangement of parts so combined as toco-act and cooperate with each other in the lper- -formance of thefunctions and the accomplishment of the results herein contemplated, andcomprises in one'of its adaptations thek species or preferred formillustrated in the accompanying drawings, in which: f

Fig. 1 is ajview in plan of a machine embodying my invention;

Referring now to these drawings, which illustrate a preferred embodimentof my invention, a support, preferably comprising a table I composed ofa wooden body 2 having a metal surfacing pl-ate3 is provided at one sidethereof with a pivot-pin 4 for the pivotal mounting of my slicingmechanism which will thus move in an arcuate path over the table I. Asshown, the pivot has a screw-threaded connectionwith a fiatsemi-circular and heavy metallicbearingplate which is suitably mountedon the table, and,..as shown, is fastened with its diametri'c' edge''registering with the edge of the table 'and its arcuate edge extendinginwardly so that the fiat surf-ace of the plate will function as a flat,hard and smooth bearing for the pivoted slicing mechanism 'during' vitsv-arcuate movement ".Said pivot, as shown, extends vupwardly Afrom saidplateatfa rightangle thereto, and-said-table isalso l`preferablyprovided-between -itsfrOntfand rear edges with position-maintaining- -orholding members vforfholdingthe product to be'sliced in-st-ationaryposition vvduring movementof vthe reciprocating 'knife -or "knivestherethrough. rIn vthe `form shown; the lproduct-'holding' member 1vcomprises al pair' vof angle- Ibars' positioned in angular` 'relation-to1 each -otherand having upright 4flanges fla -sothatabakery-productor cake 8 positioned substantiallyfatthe' center ofthe supporting table,las shown-in dotted lines in Figs. l and3,-w-ill'be maintained in 'stationary posi-tion and held from shiftingduring subsequent 1horizontal slicing thereof by the'- slicingmechanism.
